sys_attrs_ics_ll_tcp(5)


NAME

  sys_attrs_ics_ll_tcp - ics-ll-tcp subsystem attributes


DESCRIPTION

  This reference page lists and describes attributes for the internode
  communication service's low-level TCP (ics_ll_tcp) kernel subsystem. Refer
  to the sys_attrs(5) reference page for an introduction to the topic of
  kernel subsystem attributes.

  Module_Config_Name
      Kernel module configuration name (ics_ll_tcp). Do not alter the value
      of this attribute.

      Supported operations: Configure at boot time

  ics_tcp_rendezvous_port
      Port on which the ics_tcp subsystem listens for broadcasts. This port
      must be the same on all cluster nodes, and cannot be listed in the
      ics_tcp_ports array. The default broadcast port is port 900.

      Supported operations: Query; Configure at boot time

  ics_tcp_ports
      Ports available to the ics_tcp subsystem for nonbroadcast channels. The
      default set of ports includes ports 901 through 910 and ports 912
      through 917.

      Supported operations: Query; Configure at boot time

  ics_tcp_inetaddr0
      IP address of the physical cluster interconnect device (for example,
      10.1.0.1). The clu_create and clu_add_member utilities set this
      attribute.

      Supported operations: Query; Configure at boot time

  ics_tcp_netmask0
      Subnet mask used for the cluster interconnect. The clu_create and
      clu_add_member utilities set this attribute.

      Supported operations: Query; Configure at boot time

  ics_tcp_adapter0
      Name of the physical cluster interconnect device (for example, tu0 or
      nr0).  The clu_create and clu_add_member utilities set this attribute.

      Supported operations: Query; Configure at boot time

  ics_tcp_nr0
      If the ics_tcp_adapter0 attribute indicates a NetRAIN set, this
      attribute is an array listing the device names of the network adapters
      that comprise this set.

      Supported operations: Query; Configure at boot time

  ics_tcp_ipmtu0
      For clusters using a LAN interconnect, size of the maximum transfer
      unit (MTU) supported by the network to which the physical cluster
      interconnect device (ics_tcp_adapter0) is attached. Its value is
      constrained to be 1500 for 100 Mb/s Ethernet.

      Default value: 1500

      Minimum value: 0

      Maximum value: 9000
